STOCK-MARKER.

SPECIFICATION forming part of Letters Patent No. 630,349, dated August 8, 1899.

Application filed J' une 6, 1898. Serial No. 682,658. (No model.)

To @ZZ whom it may concern/.-

Be it known that I, JOHN H. HARVEY, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented a certain new and useful Improve-` ment in Stock-Markers, of which the following is a specification.

My invention relates to stock-markers in which a couple of members are fitted and secured together, illustrations of stock-markers comprising such feature being afforded by Letters Patent No. 412,431, dated October S, 1889, and No. 547,424, dated October 8, 1895.

Objects of my invention are to provide a simple and reliable construction which can be applied without the use of a special upsettingtool, as in Patent No. 412,431, and also to avoid catching and forcing the iiesh of the anilnals ear in between two telescoping parts, as will frequently happen in using the construction of said patent, since in working with the device of the latter the long hollow stem is first inserted through a hole in the animals ear and the short hollow stem is then telescoped over the longer stem and in so doing is crowded part Way through the ear of the animal. Y f

Further objects are to avoid the accidental separation of the members, which I find in practice frequently happens where stock-- markers such as in Patent No. 547,424 arel employed, and also to provide a construction permitting the two stems to primarily wedge -together before ultimate securement and at the same time allow one stem to be crowded back and spread out within an enlarged bore portion of the other stem.

In the accompanying drawings, Figure 1 is a sectional view of the two members of the stock-marker separated. Fig. 2 is also a section showing the two members of the marker partially fastened together. Fig. 3 is also a section showing the two members of the marker together and the solid stem upset or expanded for the purpose of securing the two members of the marker together. Fig. 4 is a face view of the member of the marker having the solidstem.

The stock-marker comprises a couple` of members having telescoping stems or shanks provided with suitable heads, which are respectively brought into position at opposite sides of the ear of the animal when the two members are properly fitted together. One

`of said members is constructed with a hollow stem A, having at one end a suitable head B, formed, for example, by a plate or disk. This hollow stem is designed to be inserted and extended through a hole punched through the ear of the animal. The other member is constructed with a suitable head C, formed, for example, by a disk or plate which is provided with a solid stem D, of soft or malleable metal or metallic composition.

The bore which extendsthrough the stem A from end to end thereof may be straight or made with a gradual taper from end to end; but as a preferred arrangement and matter of further improvement its end portion a farthest from the head B is made straight or substantially so, while its oppo site end portion a gradually enlarges in diameter toward the head.

The stem D should taper from the head C, where the bore of the hollow stem is straight fromend to end, but should said bore taper or gradually contract from the head B to the end a2 of the stem the stem could be made straight, so that in either case the end portion of the stem farthest from head C can be crowded back within the bore after the solid stem'ihas been introduced within the hollow stem; but preferably and as a matter of further improvement the portion d of the solid stem nearest the head C is straight or substantially so, and from thence the stem has a short tapered portion d and beyond the latter a straight or substantially straight portion d2, or, more broadly considered, the solid stem comprises two portions of dierent diameters, the larger of the two being nearest the head O and tapering to the portion d2 of smaller diameter. When, therefore, the hollow stem is extended through theear of the animal and the solid stem is inserted Vwithin the hollow stem up to the taper or `bevel d', comparatively slight pressure of the fingers of the operator against the two heads will wedge the tapered portion of the solid stem within the bore of the hollow stem, and thereby conveniently maintain the two members together and in readiness for such instrument IOO or tool as may be employed for inallydriv-T ng the solid stem home within the hollow' stem. The stem D is of such length relatively to the stem A that when it is forced therein to the limit its end d3 will project somewhat beyond the end a3V of the hollow stem, and thereby present material which can be upset or crowded back within such space as may exist between the normal diameter of the solid stem and the wall of the enlarged bo're portion a of the hollow stem, so as to ll the latter and rigidly and eiectively secure the stems together, as illustrated by Fig. 3. Where a gripping-tool is employed for forcing the solid stem within vthe hollow stem,

it can also serve as a means for causing the end d3 of the solid stem to be upset or crowded back and expanded within the hollow stem, or when a gripping-tool is not available a hammer can be used to drive home the solid stud and force its end against a block of metal or a stone.

It' will be seen that the hollow stem is rst inserted through the ,ear of the animal and the solid stem then forced within the hollow stem, in which way there will be no danger of catching the flesh of the ear between the unitingpartsythat the fastening will be permanently secure, 'and that a special tool for uniting the members need not be employed.

What I claim as my invention is- 1. A stock-marker comprising a hollow stem provided with a head and having its bore eX- tending from end to end, and a stem provided with a head and having portions of its length of diierent diameters, the larger being adjacent to the head and being tapered to the smaller portion, and the stem as a whole being larger than the bore of the hollow stem.

2. A stock-marker comprising a hollow stem provided with a head and having its bore tapered back from the latter; and a solid stem provided with a head and made longer than the bore in the hollow stem; said solid stem being formed with a portion d2 of its length substantially straight, and having betweensuch portion and the head a portion CZ of greater diameter than the portion d2 and tapered to the same.
